Purpose: The purpose of this lab was to determine the melting point of p-Dichlorobenzene. Materials: 2 100ml beaker Thermometer Melting point tube Rubber band Hot Plate Several crystals of p-Dichlorobenzene Glass Runner Ring Stand Extension Clamp Triple Arm Clamp Apparatus: See Attached Sheet Procedure: 1) Fill a beaker with several pieces of ice and water. Place the thermometer into the ice water submerging the reservoir of alcohol. Keep submerged until the liquid in the thermometer stops its decent. Record the temperature at which the thermometer read. 2) Construct the apparatus, (see diagram on other sheet). 3) Place the ice filled beaker aside. Turn the hot plate on to a setting of ten.
